AUXILIARY RUDDER FOR VES'SELS.

SPECIFICATION forming part of Letters Patent No. 364.386, dated June '7. 1887.

Application filed Se teniber 19, 1886. SerTal No. 213,870. (No model.)

To all whom, it may concern:

Be it known that I, GEORG BERNI-IARD UL- RIOHS, a resident of Hoboken, in the county of Hudson and State of New Jersey, have invented an Improved Auxiliary Rudder for Vessels, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, in which- Figure 1 represents a top view of a vessel having my improved auxiliary rudder. Fig. 2 is a longitudinal horizontal section, on a larger scale, of said rudder. Fig. 3 is a side view of the same.

The object of this invention is to supply ves- 1 sels with means for steering them should the main rudder become broken or otherwise in jured.

The invention principally consists in supplying each side of a vessel with an unattached plate or frame, a blade pivoted to said frame, which blade can be set to present a flaring mouth to the water in front, all as hereinafter more fully specified.

In the drawings, the letter A represents a;

a suitable vessel. Against each side of this vessel is laid a plate, B, which is held in position, when thrown overboard, by chains or in any other suitable manner, and is not attached to the side of the vessel. 0 is a blade having the the vessel, as in the upper part of Fig. 1, it produces a flaring month, 0, between its front portion and the side of the vessel,in which flaring mouth the water is banked as the vessel advances, thereby changing the direction of c the vessel in the desired manner.

Of course, in steering a Vessel only one of the two blades 0 will be put in the position shown in the upper part of Fig. 1 and in Fig.

2 of the drawings for afiecting the course of 5 the vessel, the other blade 0 being byits pivotal connection held substantially parallel with the side of the ship, as in the lower part of Fig. 1, so as not to interfere with the course.

When this device is not in use, it is stowed away 011 the vessel,and does not interfere with the speed of the vessel; but as soon as the necessity for its use arises it is thrown overboard and the force of the water presses it against the side of the vessel,where it is held by chains or other means ready for use.

I claim- An auxiliary rudder consisting of a frame which is adapted to be thrown overboard and pressed against the sides of the vessel by the action of the water, said frame carrying a centrally-pivoted plate which presents a flaringmonth to the water in whichever direction the vessel is propelled, and means for maintaining said frame against the vessel when thrown overboard, substantially as described.
